Rent Increase CalculatorWork out a rent increase percentage, check it against 2026 rent caps and notice rules, and see what it really costs
Enter today’s rent and either the new rent or the percentage. You’ll see the monthly and yearly difference, whether the increase is legal where you live, the earliest date it can take effect, and, for tenants, whether moving would be cheaper. Landlords can see if the raise is worth the risk of turnover.

Calculate your rent increase
Can you still afford it?
Rent above 30% of gross income counts as cost-burdened; above 50% is severe.
Renew or move?
Moving has real costs. See whether a cheaper place actually saves money over your next lease.
Is the raise worth a vacancy?
A bigger increase earns more only if the tenant stays. Here’s what turnover would cost you.
Compare increase levels
Expected extra income in year one at different increases, using your turnover cost and a move-out risk that rises with the size of the raise.
| Increase | New rent | Extra / yr if they stay | Expected gain |

The next five years at this pace
The same percentage repeated every year compounds. Compare it with a 3% path and with today’s flat market.

How to calculate a rent increase percentage
To find the rent increase percentage, subtract the current rent from the new rent, divide by the current rent and multiply by 100.
Increase % = (New rent − Current rent) ÷ Current rent × 100
To go the other way and find the new rent from a percentage, multiply the current rent by (1 + the percentage ÷ 100).
New rent = Current rent × (1 + Increase % ÷ 100)
Example: a $1,531 rent going to $1,608
- Difference: $1,608 − $1,531 = $77 a month
- Divide by the old rent: $77 ÷ $1,531 = 0.0503
- Multiply by 100: 5.0% increase
- Over a 12-month lease: $77 × 12 = $924 more a year

What is a normal rent increase in 2026?
Context matters more than any single number. National asking rents were 0.4% lower than a year earlier in Apartment List’s October 2026 data, so in most markets a large renewal increase is well above what new tenants are paying.
Common in 2026’s flat market and a strong signal the landlord wants to keep you. Usually not worth fighting.
The range many landlords use to keep up with taxes, insurance and maintenance. Worth a polite counteroffer.
Check comparable listings. Near the cap in California, Oregon and Washington, and above typical market growth.
Illegal for most covered units in rent-capped states, and needs 90 days’ notice in California. Negotiate or compare moving.
How much can a landlord raise rent in 2026?
In most of the US there’s no limit for market-rate units. Only California, Oregon and Washington have statewide caps, and some cities add their own rent stabilization rules.
| Place | Maximum increase | Period | Notice |
|---|---|---|---|
| California · LA & Orange counties | 8.7% | Aug 1, 2026 – Jul 31, 2027 | 30 days (≤10%), 90 days (>10%) |
| California · SF Bay Area | 8.8% | Aug 1, 2026 – Jul 31, 2027 | 30 / 90 days |
| California · San Diego County | 8.2% | Aug 1, 2026 – Jul 31, 2027 | 30 / 90 days |
| California · Riverside & San Bernardino | 8.1% | Aug 1, 2026 – Jul 31, 2027 | 30 / 90 days |
| California · other counties | 8.6% | Aug 1, 2026 – Jul 31, 2027 | 30 / 90 days |
| City of Los Angeles (RSO units) | 3% | Jul 1, 2026 – Jun 30, 2027 | 30 days |
| Santa Ana (stabilized units) | 2.87% | Sep 1, 2026 – Aug 31, 2027 | 30 days |
| Oregon | 9.5% (10% in 2027) | Calendar 2026 | 90 days; none in first year |
| Washington | 9.683% (10% in 2027) | Calendar 2026 | 90 days; Seattle 180 days |
| New York City · rent-stabilized | 0% (1- and 2-year leases) | Leases from Oct 1, 2026 – Sep 30, 2027 | Renewal offer 90–150 days before lease end |
| St. Paul, Minnesota | 3% | Ongoing | Per lease and state law |
| Most other states (e.g. TX, FL, GA, AZ) | No cap | — | Usually 30 days for month-to-month |
State caps generally exclude newer buildings (15 years or newer in California and Oregon) and some single-family homes owned by individuals, and California counts every increase in a rolling 12 months together. New York State also requires 30, 60 or 90 days’ notice for increases of 5% or more, depending on how long you’ve lived there. Always confirm whether your unit is covered with your local housing agency.
How to negotiate a rent increase
Landlords lose money every time a unit sits empty, so a reliable tenant has more leverage than most people think, especially in a flat market.
Find three to five similar units nearby. If they rent for less than your proposed new rent, say so with links.
A longer lease, on-time payment history or handling minor upkeep yourself can justify a smaller increase.
“Could we meet at 3%?” works better than “That’s too much.” Split-the-difference offers are often accepted.
Negotiate as soon as you get the notice, before the landlord has spent money advertising the unit.
“Thanks for the renewal offer. I’d like to stay. Similar two-bedrooms on our street are listed at $1,525 to $1,560, and I’ve paid on time for three years. Would you consider a 3% increase instead, with a 14-month lease?”
How much should a landlord raise rent?
The right increase covers your rising costs without pushing out a good tenant. One turnover can easily cost a month or more of rent, plus cleaning, repairs and leasing fees. With the calculator’s defaults, a 5% raise on $1,531 brings in about $919 more a year, but a single turnover costs about $4,288. If more than about one tenant in five would leave over it, the increase loses money. Use the landlord tab above to test your own numbers, and check what the rent does to your returns with the rental property calculator. For a multi-unit building, the NOI calculator shows how much a rent increase adds to net operating income and to the building’s value at today’s cap rates.
Check current listings before every renewal. In a market where rents are falling, a big increase invites a move-out.
Higher property tax and insurance are easy to explain. Show the numbers if you can.
Early notice reduces surprise and gives the tenant time to agree rather than search.
Larger adjustments are often easier to make on turnover, when the unit is newly listed at market rent.

Rent increase questions
How do I calculate a rent increase percentage?
Subtract the old rent from the new rent, divide by the old rent and multiply by 100. Going from $1,500 to $1,575 is $75 ÷ $1,500 × 100 = a 5% increase.
What is a 5% rent increase on $1,500?
$75 a month, making the new rent $1,575. Over a year that’s $900 more.
How much can a landlord raise rent in 2026?
In most states there is no limit for market-rate units. California caps most covered units at 8.1% to 8.8% depending on region (August 2026 to July 2027), Oregon at 9.5% and Washington at 9.683% for 2026. Rent-stabilized units in cities like New York and Los Angeles have lower limits.
Is a 10% rent increase normal?
No. With national asking rents roughly flat in 2026, a 10% increase is well above market in most places. It also exceeds the 2026 caps in California, Oregon and Washington for covered units.
How much notice does a landlord have to give for a rent increase?
It depends on the state. California requires 30 days for increases of 10% or less and 90 days above that; Oregon and Washington require 90 days (180 in Seattle); New York requires 30 to 90 days for increases of 5% or more. Many other states default to 30 days for month-to-month tenancies.
Can a landlord raise rent during a lease?
Generally not during a fixed-term lease unless the lease itself allows it. Increases normally take effect at renewal or, for month-to-month tenancies, after proper written notice.
What is the average rent increase per year?
Historically, rents have often risen about 3% to 5% a year, but 2026 is unusually flat: Apartment List measured national asking rents 0.4% lower than a year earlier in October 2026. Renewal increases for existing tenants vary widely by market.
How often can a landlord raise rent?
In Oregon and Washington, once every 12 months and not in the first year. California counts all increases in a rolling 12-month period against the cap. Where no law applies, it’s usually once per lease term.
What can I do if my rent increase is illegal?
Point the landlord to the specific limit in writing, pay the lawful rent amount, and contact your local housing department or a tenant rights organization. Keep copies of your lease, the notice and all correspondence.
How do I calculate the new rent from a percentage?
Multiply the current rent by one plus the percentage as a decimal. A 4% increase on $1,800 is $1,800 × 1.04 = $1,872.
Is it cheaper to move than to accept a rent increase?
Only if the monthly savings over your next lease exceed moving costs, fees and any overlap in rent. On a $77-a-month increase, $1,750 of moving costs takes about 23 months to recover, so renewing is often cheaper unless the alternative rent is much lower. If you move mid-month, work out the partial month with the prorated rent calculator.
Is this rent increase calculator free and private?
